The invention discloses a construction method for a deep foundation pit of a seaside circulating water pump house, and relates to the field of building construction. Comprising the following steps of surveying and setting out, field flattening within a foundation pit excavation range, precipitation well construction, slope top platform hardening, guardrail erection, primary slope earthwork excavation, side slope net spraying construction, first-layer precipitation well and drainage ditch construction, first-layer platform field hardening, secondary slope earthwork excavation, steel sheet pile construction, guardrail erection, excavation to a second layer and first inner support erection. Earthwork is excavated to a second inner supporting layer, a second inner support is erected, a foundation pit is excavated to the position 0.2 m above the designed elevation of a base, a dewatering well is constructed, the base is manually cleaned, a base drainage ditch and a sand basin are constructed, foundation construction is conducted, backfilling is conducted to the position 1 m below the second layer of support, the inner supports are dismantled, structure construction is conducted, backfilling is conducted to the position 1 m below the first layer of inner support, the inner supports are dismantled, and structure construction is conducted. And backfilling to the first platform layer, pulling out the steel sheet piles, performing structural construction, and backfilling to the field level elevation.
本发明公开了一种海边循环水泵房深基坑施工方法，涉及建筑施工领域，包括以下步骤：测量放线、基坑开挖范围内平场、降水井施工、坡顶平台硬化、护栏搭设、一级坡土方开挖、边坡网喷施工、第一层降水井及排水沟施工、第一层平台场地硬化、二级坡土方开挖、钢板桩施工、护栏搭设、开挖至第二层、架设第一道内支撑、土方开挖至第二道内支撑层、架设第二道内支撑、基坑开挖至基底设计标高以上0.2m、降水井施工、人工清底、基底排水沟及沉沙池施工、基础施工、回填至第二层支撑以下1m、拆除内支撑、结构施工、回填至第一层内支撑以下1m、拆除内支撑、结构施工、回填至第一层平台层、拔出钢板桩、结构施工、回填至场平标高。
